INtime <strong>3.1</strong> <strong>Software</strong> Scheduler Low-level calls System call knRtSleep knStartRtScheduler knStopRtScheduler Description Puts the calling thread to sleep for the specified number of kernel ticks. Cancels one scheduling lock imposed by the knStopRtScheduler function. Temporarily locks the scheduling mechanism or places an additional lock on the mechanism for the running thread. Semaphores Semaphores contain units. These system calls deal with semaphore objects and the units associated with them. RT semaphores differ from Windows semaphore objects in these respects: • Choice of FIFO or priority queuing. • A thread may wait for multiple units from a semaphore. • Multiple-object waiting is not supported. • High-level semaphores differ from the low-level semaphores in the following respects: • High-level semaphores have parameter validation. • Multiple units may be sent to and received from high-level semaphores. • High-level semaphore may be created with any initial count other than one or zero (low-level semaphores may be created only with zero or one unit). • Low-level handles may not be cataloged. NTX calls System call ntxCreateRtSemaphore ntxDeleteRtSemaphore ntxWaitForRtSemaphore ntxReleaseRtSemaphore Description Creates an RT semaphore. Deletes an RT semaphore. Waits for and removes units from an RT semaphore. Adds units to an RT semaphore. 124
Appendix A: INtime software system calls High-level calls System call CreateRtSemaphore DeleteRtSemaphore WaitForRtSemaphore ReleaseRtSemaphore Description Creates a semaphore with the given initial and maximum number of units. Deletes a semaphore. Waits for and removes a specified number of units from a semaphore. Sends a given number of units to a semaphore. Low-level calls System call knCreateRtSemaphore knDeleteRtSemaphore knWaitForRtSemaphore knReleaseRtSemaphore Description Creates 1 of 3 kinds of kernel semaphores with 0 or 1 initial units. Deletes a kernel semaphore. Waits for and removes a unit from the specified kernel semaphore. Sends a single unit to a specified kernel semaphore. Status NTX calls System call ntxGetLastRtError ntxGetRtErrorName ntxLoadRtErrorString ntxGetRtStatus Description Returns the status code of the last failing NTX call made in this Windows thread. Returns a pointer to a constant string. Copies a short sentence (no punctuation) that describes "Status" into the buffer at lpBuffer. Verifies whether the RT kernel is currently running. High-level calls System call GetLastRtError SetLastRtError CopyRtSystemInfo ReportRtEvent Description Returns the status code of the last failing RT system call made by this RT thread. Sets the calling thread’s last error field. Copies the contents of the RQSYSINFO segment, cataloged in the root process, into the SYSINFO structure. Collects log data in the same format as the Windows ReportEvent function, and passes it to the INtime Registry Service for logging in the Windows Registry. 125
